Evaluation of fusarioses in selected grass species [PDF]

Plant Protection Science, 2002
In the years 1999-2001 we observed the spread and harmful effects of pathogenic fungi causing the dying of some grass species in permanent grass growths. The most common and frequent cause of the dying (winter freezing injury) is the fungus Microdochium nivale known also as Fusarium nivale, or Gerlachia nivalis (imperfect stage) - snow mould.
